| Description & Applications | 16-channel analog multiplexer/demultiplexer The 74HC4066; 74HCT4066 is a high-speed Si-gate CMOS device and is pin compatible with the HEF4066B. The device is specified in compliance with JEDEC standard no. 7A. The 74HC4066; 74HCT4066 has four independent analog switches. Each switch has two input/output pins (nY, nZ) and an active HIGH enable input (nE). When nE is low the corresponding analog switch is turned off. The 74HC4066; 74HCT4066 is pin compatible with the 74HC4016; 74HCT4016 but exhibit a much lower ON-resistance. In addition, the ON-resistance is relatively constant over the full input signal range.Input levels nE inputs: For 74HC4066: CMOS level For 74HCT4066: TTL level ESD protection: HBM JESD22-A114F exceeds 2000 V MM JESD22-A115-A exceeds 200 V Multiple package options Specified from −40 °C to +85 °C and −40 °C to +125 °C |
